I. "Humidity Cube" Humidity Control Sheet (For animal specimens) Product features

◎Innovative material. Fiber type Humidity control agent Composed of natural plant fibers and polymer materials, it is safe and environmentally friendly, and harmless to animal specimens and human body.

◎Used to control the humidity of the micro-environment for preserving animal specimens. It absorbs and releases moisture in a balanced way, with high humidity control precision. Under room temperature conditions (20～25℃), the error is less than ±3%.

◎High moisture capacity and fast humidity control speed. Both its moisture absorption and release performance are superior to traditional "silica gel type" Humidity control agent ”。

◎The fiber-type humidity control material is in the form of a "card", which is easy to use and does not take up space; there is no dust or particle leakage.

II. Target Users and Humidity Control Range

◎Suitable for relatively closed environments such as animal specimen display cabinets, storage cabinets, preservation boxes, and pouches.

◎Humidity control range: humidity can be controlled in sections between RH30%～RH80%; the humidity control value can be specified by the user and customized as needed. For example: if the humidity control target is 50%, the humidity control range is 50%～55%.

III. Model/Specifications

IV. Measured Cases

○Humidity control agent set value: RH50%.

○Usage environment: Animal specimen pouch.

※The actual effect during use is related to the airtightness of the storage space, the characteristics of the stored materials, and the temperature/humidity of the environment.

V. Comparison of Humidity Control Performance

1. Humidity Control Precision

○Silica gel type humidity control materials: The error is ±5% of the target humidity;

Fiber type humidity control materials: The error is ±3%.

○Silica gel type humidity control materials: The ideal usage method generally requires "pre-adjustment" of the target space, but

Most museum storage conditions cannot implement pre-adjustment, and the external temperature/humidity environment is prone to changes, which easily leads to

Larger humidity control errors in the actual application of the humidity control agent.

Fiber type humidity control materials: No "pre-adjustment" of the target space is needed before use. It can quickly

Control the target space within the standard humidity range, easy to use, and high humidity control efficiency.

2. Humidity Control Capacity

Generally, within the target humidity range, the larger the humidity control capacity, the better the product performance.

The following table shows a comparison of the humidity control capacity of silica gel type humidity control materials from major brands used in foreign cultural relic preservation at different humidity ranges.

Note: Taking the reasonable preservation humidity range (RH50～60%) of museum collections such as calligraphy and painting, textiles, and animal specimens as an example, the performance of the "fiber type humidity control agent" is 1.8～2 times that of current foreign brands.

3. Humidity Control Rate

○The faster the "absorption and release" speed of the humidity control material, the shorter the time it takes for the container to reach humidity equilibrium, indicating better humidity control performance of the material.

○When the container is not well sealed, the air humidity will be in a dynamic process. Therefore, the role of the humidity control material is to quickly take effect after the humidity balance is broken, so that the container can return to the target humidity, and keep the relative humidity in a "stable" state.

○The "fiber type humidity control material" is sheet-like, with a large surface area in contact with the air; while the particles of silica gel type humidity control materials are in a "stacked" state in the packaging. Therefore, the humidity control rate of the "fiber type humidity control material" is faster than that of silica gel type.
VI. Reference Usage and Shelf Life

○Reference usage (standard environment): 600g～800g / 1 cubic meter volume

○Reference usage time under different airtight environments:

Well-sealed storage cabinets/display cabinets: 12 months

Generally sealed storage cabinets/display cabinets: 3～6 months

Poorly sealed drawers/preservation boxes/pouches: 1～3 months

VII. Usage Method

○Selection: According to the preservation humidity requirements of various types of cultural relics, select the corresponding Humidity Control Sheet Specifications.

○Usage: Determine the quantity based on the volume of the environment to be controlled and the specifications of the humidity control pack.

○Directions: Open the sealed bag and place the humidity control pack directly into the environment to be controlled.

○Check: Use a hygrometer/thermometer or humidity indicator card to observe the humidity level of the controlled environment.

VIII. Precautions

○Ensure the controlled environment is sealed, otherwise the desired humidity control target may not be achieved.

○After opening the sealed bag, use promptly or re-seal for storage to prevent loss of effectiveness.

○Replace promptly when the service life expires or when humidity regulation has no effect for more than one month.
